Environments with pH values below 7.0 are considered acidic, whereas those with pH values above 7.0 are considered basic. Extreme pH affects the structure of all macromolecules. The hydrogen bonds holding together strands of DNA break up at high pH. Lipids are hydrolyzed by an extremely basic pH.
In natural environments , decreasing or increasing the environmental pH by one unit can also lower the metabolic activity of microbial communities by up to 50% (Kotsyurbenko et al.
2004 Fernández-Calviño and Bååth, 2010).
3/4/2020 · Data suggests that the coronavirus IBV employs a direct, low-pH-dependent virus-cell fusion activation reaction. “Fusion of the coronavirus IBV with host cells does not occur at neutral pH and that fusion activation is a low-pH-dependent process, with a half-maximal rate of fusion at pH 5.5. Little or no fusion occurred above a pH of 6.0 .”, The microorganism grows at pH 1.3–2.2 at temperatures between 15 and 45 °C, uses ferrous ions as a sole source of energy, and fixes CO 2 as the sole carbon source. Ferroplasma species constitute some of the most abundant genera in environments of very low pH and are heavily charged in metals such as iron, copper, arsenic, cadmium, and zinc.
